MECHANICAL MOVEMENT AND POWER-TRANSFORMER.

Applcationled September 4, 1917.

To all whom it may concern.'

Be it knownithat \ve, Isinon M. JAcoBs and TILLIAM CnAMnn, citizens 'of the United zStates, saidIsiDon M. J .acens residing at the city of Kansas City, county of Jackson, and State of Missouri, and said VVlLLrAMuiv .Men residing at the city' of St. Louis, inthe State of Missouri, have ,invented certain new and useful Improvements in IMechanical Movements -and vPower-Transformers, of which the following isa specification.

This invention is ainechanical. movement and power transformer, and `is herein shown and described as utilized in connection with the transmission of a motor-vehicle; but it will be found suitableffor widely varied situations and `various usef'ulpurposes. 'One of the subsidiary velements o'l' themain de- '.,vice is in itself alinechanical 'movemenh `adapted for uses-other thanthose herein shown and described in eom'iect-ion with the main device, as, for instance, Aas a speedeh ange gear-shift in a motor-vehicle.

'Figure l is an elevation;

Fig. 2 is like Fig. 1, butwith the face #of the casing removed;

Fig. 3 isla section on the line 3-3 in Figs. 1, Q, and a;

Fig. it is an elevation of the opposite side from that shown in Fig. l;

Fig. 5 is a toppl'an diagrammatic view of a noter-vehicle such, for instance, as a truck;

Figs. (3 to 17, both inclusive, are diagrammatic views of alnuniber of possible positions and combinations of the gears and shafts illustrated in Figs.` 2 and 3; and

The relative position and function of this device when used in a motor-vehicle is depicted in Fig. 5, in which the casingI 1 is lshown borne by the cross-piece 2 midway between the sides 3 of the chassis and,'also, midway between the engine L and differential 5, mounted on the rear axle G.

A haspyring, or liooki17 projectingfrom member 1li receives screw-member -1'8,l1av ing the head 19, Ascrew'-threads `Q0, and wrench-end 21, ywhich screw-member 1S passes through the internally screw-threaded collar 22 lixed'to lid E11.l A partial turn with a Wrench uponthe end 21 (by'reason of cooperation of'thethreads -within collar 22 and theE threads '20) lrocks the member '11 `on pivot or sliaftfl, and' the degree of movement ofimemb'erfl-l depends upon the degree of movement of screw E18,fand the direction of the'saidfmovement depends upon the direction in 'which screw lSfisfturned. The degree of movement of member ll-L deter- `mines whiehiof the gearsfborne or actuated thereby shall mesh `wth'the other gear not carried thereon or actuated thereby.

Gear-S32, 33,' and 34 are respectively'lixed `to shafts 23, 211, and "25. lThe variety of combinations depicted inFigs. G to 17 intlicates thatordinaryobjects will be subserved by the three gears mounted on' three shafts showniirthe drawingsherein. Figs. 16'and 17 show gears 33l and 34 in two neutral positions, in both which cases the=engine 4 `is 'connectecl directly to differential15f through eonnecting-rods' and 36, universal joints '37 andf38, polygonal endsLQand 29,-and

be empirically determined; but a record be! l' ing kept of names or other identifying data the knowledge thus experimentally acquired can be instantly applied in subsequent cases. It will be observed that the arrangement of gears in Fig. 2 coincides with that in.

- Shaft 23 is journaled in box 10 and lid 11, but. shafts 24 and 25 pass through an opening in box 10 and an opening in lid 11. large enough for some rocking movementY Vof member 14 and ofthe said shafts, and

shafts 24 and 25 are journaled in rockable member 14 and carried thereby in its movement when rocked on pivot 13.

Member 14 extends through casing 1 and projects on both sides thereof, and is a solid and substantial and strong body, adapted to afford a firm support for shafts 24 and 25 and gears 33 and 34. 'In Figs. 1, 2, and 3,.

member 14 is shown protruding through openings 39 and 40 in boX 10` and lid 11, respectively, and having space in the said openings for its movement up or down when rocked; but in Fig. 18 the said openings are closed, box 10 and lidy 11 have solid walls,

chronously with the one to which each is connected. Disconnection of a socket-piece 41 or 42 from-the polygonalend inserted in it must be begun by first disconnecting` shaft 35 or shaft 36, respectively, at its opposite end, that is to say, from engine 4 or differential 5. Y

A pierced stud 43 projects from one side of box-10, affording a journal in line with the holesl in lugs 15 and 16 for shaft 13.

When engine 4 and differential 5 fail in any respect to match, as, for instance, if the engine is designed to turn clockwise but-the differential anti-clockwise, or if the Vengine is too speedy or too powerful or too slow or,V fails to develop .sufhcient power, such discrepancy can be rectified or such speed or power can be reduced or increased, according to need orfdesire, by so combining gears 32, 33, and 34 and their respective Vshafts in such manner as'to obtainthe de- 'Venid 26, 27, or 28 or the Vsocket 42 over the this power transformer.

appropriate end 29, 30, or 31, thereby forming one of thek combinations delineated in Figs. 6 to 17 for the transmission of power from engine 4 to differential 5. The device as thus used is a power transformer as well as transmitter.

More specifically stated, this invention is intended to afford opportunities for using the large and increasin number of second-V hand engines and di erentials and other parts of the motor power-plants of used pleasure motor-cars or the like in the construction of low-priced trucks and tractors and tractor-trucks. In essence, it is not necessary that the engines used shallV be second-hand or that they Vshall have come from pleasure cars or be of that type.; but the problem solved and the commercial and industrial end attained by this invention is that itY affords an outlet or use for an immense number of second-hand internal com- 4bustion engines that are nowV for sale but ket. To a certain extent, this inventionr mayV be used in conjunction with the frames of cars or trucks already standard 1n certain sizes on the market, but this invention con- Y templates as a general practice the use 'of a standard truck or tractor frame specifically.

constructed Vand provided for the abovestated purposes, which standard frame will be of uniform dimensions andsizes suitableA for trucks or the like. Y

As a general rule, it is not desired that trucks, tractor-trucks, and the like shall be capable of as great speed as pleasure cars, while they need more power, and this constitutes one of the reasons for the provision of the herein-described Y though in practice t e eXigency has, also, arisen of driving a differential adapted to rotate in one direction by means ofV an engine adapted only to drive a differential adapted for the opposite rotation. This has been successfully accomplished by means of y Furthermore, the vario gears and shafts shown in Figs. 6 to 17 make it possible to combine practically all known engines with all known differentials. While the combinations shown in Figs. 6to 17 are believed to be practically complete, yet limitation thereto is not desired. With respect to the Varrangements shown in Figs. 6to 17, speed is Vaffected only by the combinations shown in Figs. 6, 7, 10, 11, 12, 13, 14, and 15.

Moreover, by the use of this device, the number of revolutions of a high-speed enower transformer, al`

us combinations of gine will be cut down so as to fit such vrelatively slow speed of theV differential as is suitable for trucks, tractors, andthe like, with a consequent saving of gasolene. Thus, a Ford pleasure car is, without this ,device,

geared four to one, while inia truck it should be geared seven toene, which change can be effected by the interposition of this power transformer.
